Fig; 15 is a diagrammatic view of an' electricj circuit including meansfor heating folding devices,; heat sealingrollers, and wax containersshown in preceding Referring to the drawings, wherein like reference'characters designate like parts throughout at the rear thereof andjournalled in suitable clutch part 21 with, and disengage the severalviews, v5 and 6 indicate the side frames of the machine, which areconnected together by cross members 7 and have legs 8 that are bolted orotherwise suitably secured on the machine foundation 9. The variousmovable parts of the machine are mounted on the above describedframework and said parts are preferably driven from a common source ofpower, herein shown as an electric motor 10 which is bolted or otherwisesuitably secured on the side frame 5 at the bottom thereof. This motor10 is supplied with current from any suitable source, and said motor.may be stopped or started, as desired, by a suitable switch (not shown).

Fixed on the armature shaft 11 of the motor 10 is a pulley 12 aroundwhich passes a belt 13. The belt 13 also passes around a pulley 14 whichis fixed on one end of a shaft 15 that extends transversely of themachine, and is journalled in suitable bearings on the side frames 5 and6 thereof. Fixed on the opposite end of the shaft 15 is a pulley 16around which passes a belt 17 the tension of which is regulated, asdesired, by a tension roller 18 mounted on the side frame 6 of themachine in any suitable manner. The belt 17 also passes around a pulley19 that is fixed on a shaft 20 extending across the machine at the topand rear thereof and journalled in suitable bearings on the side frames5 and 6. This shaft 20 constitutes the main drive shaft of the machine,and said shaft is continuously driven through the described drivingconnections therefor with the motor 10.

Mounted on the shaft 20 is a clutch of any suitable type including apart 21 which is splined on said shaft to rotate therewith and movetherealong, and a part 22 which. is loosely mounted on said shaft androtated thereon upon engagement of the clutch parts 21 and 22. Theclutch part 21 is moved into and out of engagement with the clutch part22 by a lever 23 which is pivoted at 24 on the framework of the machine.The lever 23 is pivotally connected at 25 with a rod 26 extendingtransversely of the machine through suitable bearings on the side frames5 and 6 thereof. This rod 26 is provided at its opposite ends with knobsor handles 2'7 by means of which the rod may be moved to swing the leverand engage the said part from, the clutch part 22.

The clutch part 22 has secured to, or formed integrally therewith, apinion 28 which meshes with a gear 29 that is fixed on a shaft 30extending transversely of the machine and journalled in suitablebearings on the side frames 5 and 6. This shaft 30 also has fixedthereon a pinion 30 which meshes with a gear 30" loosely mounted ontheshaft 20. The gear 30" has secured thereto, or formed integrallytherewith, a sprocket 31 around which passes a chain 32 that also passesaround an idler sprocket 32' Journalled and adjustably mounted in anysuitable manner on the side frame 5. The chain 32 also passes around asprocket 33 which is fixed on a shaft 34 extending transversely of themachine bearings provided by brackets 34 bolted or otherwise suitablysecured on a spacer 34" between conveyor ways 39. The shaft 34 also hasfixed thereon sprockets 35 around which pass chains 36 which extendlongitudinally of the machine between the side frames 5 and 6 and passaround sprockets 37.

The sprockets 3? are fixed on a shaft 38 which extends transversely ofthe machine and is Journalled in suitable bearings provided by brackets37' bolted or otherwise suitably secured on the front ends of the ways39. The ways 39 project forwardly from the frames 5 and 6 and extendlongitudinally of the machine between said frames. These ways 39 arebolted or otherwise suitably secured to certain of the cross members 7which extend between said ways. The chains 36 and a plurality of cartonforms carried thereby, are thus driven continuously from the shaft 20when the clutch parts 21 and 22 are connected by the described means forthis purpose. The forms 40 are secured to, or have formed integrallytherewith, base plates 41 which are fastened to the chains 36 in anysuitable manner at intervals along the same. During travel of the chains36 and the forms 40, the base plates 41 of the latter are received insuitable guides 39" on the ways 39 and which serve to guide the formsand maintain them in proper position.

In accordance with the present invention, blanks 42 (Figs. 1 and 4) arefed into the path of travel of the forms'or supports 40 and formed intocontainers thereon by mechanism including movable means for folding andheat sealing said blanks. These blanks may be of paper or other suitablematerial impregnated with, or having applied thereto, a substance whichupon application of heat to overlapping portions thereof, will beeffectively sealed through the medium of said substance. As hereinshown, blanks 42 of waxed paper are employed in the making of bags orliners A (Fig. 9) that are formed on the supports or forms 40, and saidblanks are fed into the path of travel of said forms by mechanism suchas disclosed in Patent No. 1,674,920, granted June 26, 1928, to G. A.Robinson.

Accordingly. the shaft 38 has mounted thereon, a sprocket 39 aroundwhich passes a chain 40' that passes under an idler sprocket 41' whichserves to regulate the tension on said chain and is journalled andadjustably mounted in any suitable manner on the side frame 6. i'.hechain 40 also passes around a sprocket 42 which is fixed on a shaft 43extending transversely of the machine and journalled in suitablebearings on the side frames 5 and 6. Loosely mounted on the shaft 43,and driven from said shaft through a suitable clutch 38' (Fig. 4)thereon, is a sprocket 43' around which passes a chain 44. This chain 44also passes around a sprocket 45 which is fixed on a shaft 46-extendingtransversely of the machine and journalled in suitable bearings onbrackets 4'7 that are bolted or otherwise suitably secured to the sideframes 5 and 6 at the top thereof (Fig. 1). This shaft 46 has fixedthereon a roller 48 provided longitudinally thereof on its circumferencewith a groove 49 (Fig. 7). The shaft 46 also has fixed thereon a pinion50 which meshes with a gear 51 that is fixed on a shaft 52 extendingtransversely of the machine and journalled in suitable bearings on thebrackets 47.

Fixed on the shaft 52 is a roller 53 provided longitudinally thereof onits periphery with a cutter 54 which enters the groove 49 of roller 48during each revolution of the latter and the roller 53. Fixed on theshaft 46 at the end thereof opposite that carrying the pinion 50, is agear 55 which meshes with an idler gear 56 that is journalled on one ofthe brackets 47. This idler gear 56, in turn, meshes with a gear 57 thatis fixed on a shaft 58 extending transversely of the machine andJournalled in suitable bearings on the feed roller 60 is driven by gears57, 61- fixed on shaft 58 and meshing with gears 61" fixed on shaft 61.The upper feed roller 60, the lower feed roller 59, the roller 53 andcutter 54 thereon, and the roller 48 are thus driven continuouslythrough the described driving connections therefor with the shaft 38.

Bolted or otherwise suitably secured to the machine foundation 9, areframes 62 (Fig. 1) that carry vertically extending supports 63 the lowerends of which are bolted or otherwise-suitably secured to said frames.The upper ends of the supports 63 are secured in any suitable manner tocorresponding .ends' of horizontally extending supports 64 the oppositeends of which are secured in any suitable manner to the brackets 4'7.Journalled in suitable bearings on the frames 62 'isa shaft 65 on whichis mounted a roll 66 of waxed paper. A web 67 from this roll is ledupwardly around a roller 68 onthe supports 63, then horizontally arounda roller. 69 on the supports 64, and then downwardly and horizontallybe- :tween the feed rollers'59 and 60 from which the web is ledhorizontally between the rollers 48 and 53. The :web is then guideddownwardly by guides 48 between the roller 48 and pressure rollers "70cooperating therewith, said pressure rollers being mounted in anysuitable manner on a vertically extending plate '71 which carries saidudes.

The plate '71 is bolted or otherwise suitably secured to the side frames5 and 6 and. the brackets 4'7, and said plate is provided near thebottom thereof with an opening "72 through which the plate 11 and theguides '73, whereupon the cutter 54'cuts a blank 42 from said web atthetime the leading edge of the web is seized between low speed rollers75 .and pressure rollers '76 cooperating therewith. The low speedrollers '75 are-fixed on a shaft 7'7 extending transversely of themachine and journalled insuitable bear? ings on the brackets 47,said'rollersand said shaft being driven by a sprocket '78 fixed on thelatter and over which the chain 44 passes. The ressure rollers '76 aremounted on the plate "71 in any suitable manner and extend throughsuitable openings in said plate for engagement with the blank 42 andthelow speed rollers '75. The blank 42 is fed downwardly by the lowspeed rollers 75 and the pressure rollers "76, between high speedrollers '19 and pressure rollers 80, said high speed rollers being fixedon a shaft 81 journailed in suitable bearings on brackets 82 that arebolted or otherwise suitably secured to the side frames'5 and 6 at thetop and corresponding end portions thereof.

84 that also passes around a'sprocket adwhich is blank is coated orimpregnated.

The high speed rollers are v driven throughthe medium of a sprocket 83fixed on the shaft 81 and around which passes a chain.

fixed on the shaft 43. The pressure rollers are mounted in any suitablemanner on the plate '71 and extend through suitable openings therein forengagement with the blank 42 and the high speed rollers '79.

The blanks 42, cut one after another by the described means for thispurpose, are delivered in livered in front of each form 40 across theopening '72 and onto supports or stops 86, 'just before the form passesthrough said opening. The supports or stops B6 are arranged at oppositesides of the opening '72 and said supports or stops are bolted orotherwise suitably secured onthe plate 71 near the bottom thereof.

As each form 40 moves through the opening '72 in plate '71, the blank 42in front of said form is forced thereby through said opening and foldedaround the front and opposite sides of the form by rollers 87 extendingvertically at opposite sidesof the opening '72 and journalled in anysuitable manner on the plate '71 (Fig. 4). Brushes 88 between which theform passes, then engage opposite sides of, the blank and hold itagainst the form until folding mechanism, to be presently described,folds and seals the blank-on the back of the form. The brushes 88 arecarried by holders 89 that are mounted in any suitable manner on theplate '71 (Fig. 6).

In accordance with the present invention, the waxed paper blank 42 ismade into a liner or container on the form 40, by means includingmovable devices that both fold and heat seal said liner or container. Asherein shown, the panels 90 of the containers A are folded around theforms 40 by cold folders 91, and the panels 92 of said containers arefolded around said'forms by hot" folders 93, said folders movingcontinuously in closed paths in timed relation with the continuouslymoving forms 40, and the folders 93 actin to heat seal overlappingportions of the panels 90 and 92 so that each liner or container A issealed along one side thereof through the medium of the wax with whichthe container formin The folders '91 are preferably operated, mounted,and constructed as follows.

r 1 Fixed on'the shaft 43 is-a sprocket 94 around. which passes a chain95 engaged by anidler 96- which serves to maintain proper tension onsaid chain and is mounted on the machine framework in any suitablemanner. The chain 95 also passes around a sprocket 6'7 which is fixed ona shaft 98 extending transversely of the machine between the ways 39 andjournalled in suitable bearings on theside frames 5 and'6. The shaft 98is thus driven continuously through the described driving connectionstherefor with the 'shaft'43. Fixed on the shaft 98 adjacent one endthereofis a bevel gear 99 which meshes with a similar gear 100 that isfixed on a verticalshaft 101 adjacent the lower end thereof (Figs. 4 and6) The shaft 101 i's'journalled in, suitable bearings onthe side frame,6. and fixed on saidshaft is a sprocket 102 around which passes achain,103,engaged by an idler sprocket 103' mounted on the side frameGin.

any suitable manner and serving tomaintain proper tensionbn said chain.The chain 103 also passes around-a sprocket 104 that is fixed on a shaft105 extending vertically between ways 106' able means on upper and lowerbrackets 107 and 108 respectively which are bolted or otherwise suitablysecured on the side frame 6 (Figs. 1, 2 and 4). I

Fixed on the shaft is a sprocket 109 around which passes a chain 110that also passes around a sprocket 111. The sprocket 111 is fixed on ashaft 112 which extends vertically between the ways 106 and isjournalled thereon in any suitable manner. The cold folders 91, hereinshown as four in number, are secured to the chain 110 at intervals alongthe same, and said folders and said chain are driven continuously in aclosed or endless path by the described driving connections for thechain with the continuously driven shaft 98. The folders 91 areidentical as respects mounting, construction, and operation, and it istherefore only necessary to describe one of said folders. Each folderincludes a vertical tubular boss 113 (Fig. 11) having secured thereto orformed integrally therewith spaced parallel plates 114 extending overthe chain 110 and secured thereto as by pins 115 which passthroughcertain of the links of said chain. Journalled on the pins 115and retained against displacement therefrom in any suitable manner, arerollers 116 which travel in suitable guides 117 formed on the ways 106at the tops and bottoms thereof, respectively.

Journalled in the boss 113 is a'shaft 118 having arms 119 and 120 fixedon the upper and lower ends thereof, respectively. The arm 120 hasjournalled thereon in any suitable manner, a roller 121 which extends inthe groove 122 of a cam 123 made in the form of an elongated plate ofirregular configuration and secured in any suitable manner to thebrackets 108 below, and 1 in spaced relation with, the ways 106. Pivotedat 123' on the arms 119 and 120, are folder arms 124 on correspondingends of which are mounted the folder 91. As herein shown, the folderproper is comprised by a small vertically extending shaft 125 mounted onthe folder arms 124 and carrying ribbed rollers or the like indicated at126. Shaft 125 and the rollers 126 are retained against displacementfrom the folder arms 124 by any suitable means for this purpose, andsaid folder arms have pivotally connected therewith, as at 127,corresponding ends of links 128 the opposite ends of which have pin andslot connections 129 and 130, with arms 131 that are secured to orformed integrally with the boss 113. The arms 119 and 120 have securedthereto, as by clips 131', corresponding ends of springs 132 theopposite ends of which are secured, as by pins 132', on the links 128adjacent the slots therein. During travel of the chain 110 and thefolders 91, the latter are operated, through engagement of the roller121 with the cam 122, to fold the panels 90 of the blanks 42 on theforms 40, as before pointed out. The links 128 and the springs 132normally maintain the folders at right angles to the arms 119 and 120,but provide for yielding movement of .said folders to insure engagementof the same with the forms 40 and prevent damage to the folders.

The folders 93, as previously pointed out, fold the panels 92 of theblanks 42 on the forms 40, and said folders are preferably operated,mounted, and constructed as follows: Fixed on the continuously drivenshaft 98 at the end opposite that carrying the bevel gear 99, is a bevelgear 133 which meshes with a similar gear 134 that is fixed on avertical shaft 135 adjacent the lower end thereof (Figs; 2, 4 and 6).This shaft 135 is journalled in suit-,

able bearings on the side frame 5. and said shaft has fixed thereon asprocket 136 around which passes a chain 137. An idler sprocket 138engaging the chain 137 serves to maintain proper tension thereon, andsaid idler sprocket is journalled in any suitable manner on the sideframe 5 of the machine. The chain 137 also passes around a sprocket 139that is fixed on a vertical shaft 140 extending between ways 141 andjournalled thereon in any suitable manner. The ways 141 are secured inany suitable manner to upper and lower brackets 142 and 143respectively, which, in turn, are bolted or otherwise suitably securedto the side frame 5 of the machine (Figs. 1, 2 and 4).

Fixed on the shaft 140 is a sprocket 143 around which passes a chain 144that also passes around a sprocket 145. This sprocket 145 is fixed on ashaft 146 which extends vertically between the ways 141 and isjournalled thereon in any suitable manner. The folders 93, herein shownas three in number, are secured to the chain 144 at equal intervalsalong the same, and said folders and said chain are driven continuouslyin a closed or endless path through the described driving connectionsfor the chain with the continuously drivenshaft 98. The folders 93, asrespects their mounting, construction, and operation, are identical andit is therefore only necessary to describe one of the same.

Each folder 93 is carried by a vertically extending tubular boss 147which has secured thereto, or formed integrally therewith, spaced plates148 that are engaged over the chain 144 and secured thereto, as by pins149 which extend through certain of the links of said chain (Figs. 12,13 and 14). Journalled on the pins 149, and retained againstdisplacement therefrom by any suitable means for this purpose, arerollers 150 which travel in suitable guides 151 on the ways 141.Rotatably mounted in the tubular boss 147 is a shaft 152 having fixed onthe upper and lower ends thereof arms 153 and 154, respectively. The arm154 has journalled thereon a roller 155 which extends in the groove 156of a cam 157 comprised by an elongated plate of irregular configuration(Fig. 4). This cam 157 is secured in any suitable manner on the brackets143 below the ways 141 and in spaced relation therewith.

Journalled in suitable openings in the arms 153 and 154 are pins 158which project through said openings from opposite sides of said arms andhave arms 159 and 160 that are rigidly secured on the pins 158 inalinement and turn therewith on the arms 153 and 154, respectively. Thearms 160 have pivotally connected therewith corresponding ends of links161 the opposite ends of which have pin and slot connections 162, 163with arms 164 that are secured to or formed integrally with the boss147. Secured. as by pins 164' to the links'161 adjacent the slots 163therein, are corresponding ends of springs 165 the opposite ends ofwhich are secured, as by clips 166, to the arms 153, 154, at the freeends thereof. The arms 160 have secured thereto in any suitable manner,arms 167 of a plate 168 on one edge of which is riveted or otherwisesuitably secured the folder 93. The links 161 and the springs 165normally maintain the folders 93 at 92 of the blanks 42, in overlappingrelation on m,

the back of the forms 40, as previously described, and the folders '93are, in accordancev with the present invention, heated so that saidoverlapping panels or portions are heat sealed through the mediumof thewax or substance with which the blank is coated or impregnated.Accordingly, the folders 93 are preferably heated electrically throughthe medium of heat elements ap plied thereto and travelling therewith,and the current for heating said elements may be supplied thereto fromany suitable source. As herein shown, a generator 169 (Fig. 15) having aground lead 170, is connected by a lead wire 171 with a contact 172provided on a switch panel .173 made of suitable insulating material andmounted on the side frame 5 of the machine in any suitable manner. Theswitch panel 1'73 also has mounted thereon a switch 1'74 movable intoengagement with the contact 172 and connected by a lead wire 175 withthe resistance element 176 of a rheostat 1'77. This rheostat 177 isemployed to vary the current in the heaters on folders 93, as desired,and includes an arm 1'7'7 movable along the' element 1'76 in engagement.therewith and connected by a lead wire 1'78 with an elliptical track1'79 of copper or other suitable material mounted on'a plate 180 of'similar configuration and insulated therefrom inany suitable manner.(Figs. 1, 2 and4).

The plate180 in turn, is mounted in any suitable manner on the brackets142 above the ways 141, so that the track 179 is disposed in positionfor engagement by brushes 181 which are mounted on the folder-carryingbosses 147 and travel around said track in engagement therewith as thefolders 93 are moved continuously along their closed or endless path bythe described means for this purpose. The brushes 181 extend in suitableslots formed in fiber blocks 182 which, together with said brushes, aresecured in any suitable manner on fiber supports 183 at'the upper endsthereof (FigsQl, 2, 4, 12 and 13). The lower ends of the supports 183are secured in any suitable manner on arms 184 which, in turn, aresecured to, or formed'integrally with, the bosses 147.

The brushes 181 have connected therewith, as at 185, lead wires 186which are connected with lead wires 187. The lead wires 186 and 187, in

.turn, are connected at 188 with the arms 159 and areinsulated,therefrom in any suitable manner. The lead wires 187 are also connected,

as at 189, with corresponding ends of resistance elements 190 enclosedin heaters 192 and insulated therefrom in any suitablemanner. The

heaters 192 are secured" in any suitable manner lead wires 18'! areconnected, as at 194, with lead 7 wires 195 which, in tum; areconnected, as at 196, with the lowermost arms, 167 and thus grounded onthe folder carrying means. It will appear, from the foregoing, that whenthe switch 174 is closed, current will be supplied to the refolders 93-during operation of the same by the described mechanism for thispurpose.

The forms 40' and the folders 91 and'93 travel continuously in timed.relation that said with the back of the form '40. The folder'91 is .thenmoved outwardly a slight distance through of the roller 155 with a dwell199 in the cam 15'7.

folders fold in and overlap portions of the blanks on the formssuccessively and heat seal the overlapping portions of said blanks inlike manner. 1 Accordingly, as a form 40 with a blank wrapped around thefront and opposite sides thereof moves between the cams 123 and 157, oneof the folders 1 91 and one of the folders 93 act to fold in, overlap,and heat seal the blank on the back of the form, as stated. The folder91 is first moved inwardly through motion imparted thereto by engagementof the roller 121 with a dwell 198 (Fig. 4) in the cam 123, so that saidfolder engages the panel or portion of the blank 42 and swings saidpanel or portion into engagement engagement of the roller 120 with adwell 198' in the cam 123, whereupon the folder 93 is moved inwardlybackof the form through engagement The folder 93 thus engages theportion or panel 92 of the blank 42, swings it inwardly of' the form inoverlapping relation with the portion or panel 90, and heat seals theoverlapping portions of the blank, whereupon the form 40 and the twofolders 91 and 93 travel forwardly together,-the folders 91 and 93engaging the blank or .liner and the form and being maintained in sideby side relation against the back of the portions of the blank or linerthereon, through engagement of the roller 121 with a dwell 203 in-thecam 122. Thereaftenthe folder .91 is moved out of engagement with theform and the blank or liner thereon, through engagement of the roller121 with a dwell 204 of the cam 122, whereupon the two folders are movedoutwardly through engagement of the rollers 121 and 155 with the camgrooves 122 and 156 of the cams 122 and .157. The two folders 91 and 93then move rearwardly and inwardly to fold in a blank 125 on a succeedingform, as in the case oi. the first described folding operation.

It will, of course, be understood that as each form passes between thecams 123 and 157, one of thefolders 91 and one of the folders 93 will 6fold the blank thereon in the manner already described. The number offolders 91, as previously pointed out, is greater than the number offolders 93, and this is preferable for the reason that it is desirableto, holdan unheated folder 91 in engagement with the overlappingportions of the. blank or liner on the back of the form after a heatedfolder 93 has been disengaged therefrom, until a sufficient time haselapsed for the wax or other substance to set and thus no insure. aperfect seal. The arrangement, construction, operation, and timingof'the folders 91, 93 and the forms 40, however, are such that onefolder 91 and one folder 93 always cooperate in the folding of a blankor liner on the back of each form 40in the manner previously described.Y Y

' The forms 40 and the blanks or liners successively pass top folding.mechanism which acts to fold'in and heat sealen'd portions of the blanks150 or liners one after another as the forms and ing plate 205 is ofirregular configuration and provided at opposite sides thereof withwings or extensions 209 and 210, respectively. This folding plate 205has secured to or formed integrally therewith spaced pairs of lugs 211in slots of which are received a holder 212 that is secured in anysuitable manner to said lugs. The holder 212, in turn, is secured to orformed integrally with a cross member 213 which extends transversely ofthe machine and is supported on the side frames 5 and 6 therefor formovement relative thereto so that the folding plate 205 may yieldablyengage the forms 40 and the blanks or liners thereon.

The folding plate 206 is mounted in any suitable manner on one of a pairof bars 216 and supported therefrom in spaced relation with the wing 210of the folding plate 205. The folding plates 207 and 208 are hinged at2141 and 215, respectively, on one of a plurality of cross bars 217adjustably connected with the bars 216. The bars 217 extend transverselyof the machine and are secured in any suitable manner to the side frames5 and 6 thereof.

As each form 40 with a blank or liner 42 thereon passes under thefolding plate 205, the front top portion 218 of said liner or blank isfolded down on the top of the form by a curved folder 210 which issecured to or formed integrally with the folding plate 205. Thereafter,the rear top portion 220 of the blank or liner is folded down on the topof the form 40 by a swinging folder 221 comprised by a roller or rollersjournalled in any suitable manner on an arm 222 that is fixed on arockshaft 223. This rockshaft 223 extends transversely of the machineand is journalled in suitable bearings on the side frames 5 and 6 at thetops thereof. Fixed on the rockshaft 223 is an arm 224 which ispivotally connected with one end of a link 225. The opposite end of thelink 225 is pivotally connected with one end of a lever 226 which ispivotally mounted at 227 on the side frame 6 of the machine. Theopposite end of the lever 226 has journalled thereon a roller 228engaged in a closed cam 229 which is fixed on the shaft 43 and shaped torock the folder 220 each time a form passes thereunder so that saidfolder folds in the rear top portion of the blank or liner under thefolder 219 and onto the top of the form. 40. A

While the forms 40 and the blanks or liners thereon pass the movable andstationary folding devices, said blanks or liners are maintained inengagement with opposite sides of the forms by brushes 230, 230, 231,231', 232, 232 and 233, 233' extending horizontally adjacent the topsand bottoms of the forms 40 (Fig. 6). The brushes 230, 231, 232 and 233are mounted on brackets 234 adjustably secured in any suitable manner onthe bars 216, and the brushes 230", 231", 232' and 233 are mounted onbrackets 234' adjustably secured in any suitable manner on the cams 123and 157. The several brushes, together with the movable and stationaryfolding devices, insure that the blanks 42 will be tightly held againstthe forms while said blanks are being formed into bags or liners orcontainers thereon. When the front and rear portions 218 and 220 of thelinerblank have been folded down on top of the form, as be foredescribed, the opposite side portions 235 and 236 of said blank areswung outwardly between folder wing 209 and brush 232 and folder wing210 and folder 206, respectively. In the continued travel of the form40, the liner flap 235 is engaged between the folder plate 207 and awing 237 of plate 205 and folded down on top of the form above the linerflaps 218 and 220, whereupon the liner flap 236 is engaged between thefolder plate 208 and the wing 237 and folded down on top of thepreviously folded liner flap 235. The closed end portions of the linersor containers are thus formed one after another by the described foldingdevices for this purpose, and as each form and liner travels forwardlyof the folding plate 208, the closed end of the liner or container isengaged and sealed by rotatable heated rolls which are preferablyoperated, mounted, constructed, and heated, as follows. i

. Fixed on the shaft 98 is a sprocket 238 around which passes a chain239 which also names over idler sprockets 240 and a sprocket 241 (Figs.2 and 6). The idler sprockets 240 are journalled and mounted on the sideframe 5 of the machine in any suitable manner and the sprocket 241 isfixed on a shaft 242 extending transversely of the ma-,

chine and journalled on the side frames 5 and 6 at the tops thereof.Fixed on the shaft 242 and driven thereby through the described drivingconnections therefor with the shaft 98, is a gear 243 which meshes witha gear 244 that is fixed on a shaft 245 driven through said gears fromthe shaft 242. The shaft 245 is journalled in suitable bearings on thearms 246 of a yoke 247 carried by arms 24B loosely mounted on the shaft242. The yoke 24'? and the parts carried thereby, are yieldablysupported from the bars 216 by a bolt 247' extending loosely through asuitable opening in one of a pair of small cross bars 247" bolted orotherwise suitably secured to bars 216. The bolt 247 has mounted thereona spring 250 disposed between the yoke 247 and the bar 247" throughwhich said bolt extends.

Fixed on the shaft 245 is a roller 251 driven by said shaft to rotate inengagement with the interfolded closed ends of the bags or containers onthe forms 40 so as to heat seal said interfolded closed ends of saidbags or containers. This driven heat sealing roller 251 is preferablyheated electrically, and as herein shown, includes a plurality ofheaters 252 which are arranged in suitable openings in said roller andhave resistance elements 253 (Fig. 15) suitably insulated from theheaters and the roller and supplied with current as follows.

The contact 172 on the switch panel 173 is connected by a bus bar 254with a contact 255 on said panel. Mounted on the panel 173 is a switch256 which is adapted to be moved into engagement with the contact 255and is connected with one end of a lead wire 257. The cpposite end ofthe lead wire 257 is connected with the resistance element 258 of arheostat 259 by means of which the current in the resistance elements253 of heaters 252 maybe varied as desired. This rheostat 259 includesan arm 260 which is movable over the'resistance 258 in engagementtherewith, and connected with the arm 250 is one end of a lead'wire 261.The opposite end of the lead wire 261 is connected with short lead wires262 and 263, the lead wire 262,

in turn, being c'onnectedwith a circular contact ring 264 looselymounted on, and insulated from,

' element 253 of meet the heaters 252 and suit-v if desired, be providedto assist in heat sealing ably insulated from said roller to preventgrounding thereon. The resistance elements 253 of the several heaters252 are connected in series, as by lead wires 266, the last heater ofthe series having its resistance element grounded on the roller 251. Itwill appear, from the foregoing, thatwhen the switch 256 is closed,current will be supplied to the resistance elements 2530f heaters 252during rotation thereof withthe roller 251,

and said roller will'thus be heated and act to heat seal the closed endsof the liners or containers as the formscarrylng them pass under saidroller. A second heated roller 268 (Figs. 2 and 4) may,

the closedends of the liners or containers, and saidroller may bepositively driven, or may operate through frictional engagement thereofwith the ends of the containers or liners and the forms 40. As hereinshown, the roller 268 is frictionally operated, and said roller ispreferably mounted, constructed, and heated as follows,

Loosely mounted on the shaft 242 and retained against endwisedisplacement thereon in any suitable manner, are arms 269 in the freeends of which are provided bearings for a shaft 2'70 on which the roller268 is fixed. The shaft 270 passes through suitable openings in the arms271 of a yoke 272. The yoke 272 .is supported from the bars 216 by abolt 273 which passes through a suitable opening in said yoke and one ofthe bars 24'7" and carries a spring 274 disposed between the yoke andthe bar 247' associated therewith. The roller 268 engages the tops ofthe forms 40 and the closed ends of the liners or her. "with one end ofthe lead wire 263 the opposite said heaters and the roller 268 andconnected in' series. by lead wires 27'? (Figs. 6 and 15). Mounted onthe roller 268 to rotate therewith, is a brush 2'77 insulated in anysuitable manner from said roller and connected with one end of the firstresistance element 276 of the series included in the heaters 2'75. Oneend of the last resistance element 2'76 of the series is grounded on theroller 268 and during rotation'of said roller, the brush 2'7'7 engages acontact ring 279 of copper or other suitable material loosely mounted onthe shaft 2'70 and insulated therefrom in any suitable manner. The ring279 is fixed on one arm 2'71 of the yoke 2'72 and insulated therefrom inany suitable man- This contact ring 2'79.has connected thereend of whichis connected with the lead wire 261, as-previously described, so thatwhen the switch 256 is moved into engagement with the contact 255current will be supplied to the resistance ele ments 2'76 of heaters 275on roller 288 as well as to the resistance elements 253 of heaters252 onroller 251. The two rollers thus act to press and.

heat seal the closed ends of the linersor con-' tions between the shafts284 and the sprockets Whenthe liners or containers have been;

formed, as above described, they may be removed in any suitable mannerfrom the forms 40, to be placed in receptacles or used in various otherways, or said liners or bags or containers may, before removal of thesame from the forms 40, have formed thereon cartons or the like whichare lined by the containers or bags or liners. In the latter case, it isdesirable to secure the liners or bags to the carton in order to preventmaterial from sifting between the two when the lined receptacles arefilled. As herein shown, the liners or bags are of waxed paper and, inaccordance with the present invention, the carton or the liner or bag,will have applied thereto heated wax or;'

other wax-like substance similar to that with which the bag or liner isimpregnated or coated, so that when the liner or bag and the carton orthe like are assembled together, they will .be secured to. each other bysaid wax, and material will be prevented from sifting in between thecarton and the bag or' liner when the receptacle is filled.

In the embodiment of the invention herein disclosed, heated wax isapplied tothe liner or bag, whereupon a carton is formed on the bag orliner. andthe latter is secured to said carton by said wax, the :waxapplying means being preferably operated, mounted, and constructed asfollows.

Fixed on the shafts 101 and 135 at the upper ends thereof, are sprockets280 around which pass chains 281 that also pass around idler sprockets282 and driven sprockets 283 (Figs. 2, 4, 6 and 8).

The idler sprockets 282 serve to regulate the ten sion of chains 281, asdesired, and said sprockets are journalled and adjustably mounted onbracke shafts between said collars and the'hubs ofthe sprockets 283. Theshafts 284 are journalled in' any suitable manner on brackets 287 whichare bolted or otherwise suitably secured on small brackets 288. Thebrackets 288, in turn, are

289 the latter, in turn, being bolted or otherwise suitably secured onthe upper way 39 at opposite sides thereof, so that the forms 40 travelbetween brackets 287 and 289 and wax applying and holding means carriedthereby, respectively.

Secured to or formed integrally with the sprockets 283, are bevel gears290 which mesh with similar gears 291 fixed on shafts 292 inclinedinwardly and downwardly toward each otherand journalled in suitablebearings on the brackets 287. The shafts 292 also have fixed thereon waxapplying disks or wheels 293 which are inclined upwardly and inwardlytoward each other and have beveled annular wax applying surfaces 294.These inclined wax applying wheels 293 extend within wax containingreceptacles 295 which are bolted or otherwise sultably secured on thebrackets 289, and said wheels are driven through the described .drivingconnections therefor with the continously driven shafts 101 and 135. If,for any reason, the machine is started when wax in the receptacles 295is con- .gealed or not sufficiently melted, said wax would 120. boltedor otherwise suitably secured onbrackets wheels and driving meanstherefor, the connec- 110 ets 283' which are secured in any suitablemansaid shafts, thus afiording slippage between the bevel gears 290 and291. When the wax in the receptacles 295 is melted, the springs 286 actto engage the bevel gears 290 with the bevel gears 291 so that the waxapplying wheels 293 are rotated, as above described. Accordingly, during the normal operation of the machine, the forms 40 with liners orcontalners thereon pass one after another between the'rotating waxapplying wheels 293 and the latter apply stripes of heated wax onopposite sides of the liners or containers. In order to insure againststicking of the liners or containers to the forms 20, when the liners orcontainers are sealed thereon and the stripes of wax are applied toopposite sides of the limbs or containers, said forms are provided onthe front, top, and rear sides thereof with corrugations 296 and on thesides with wood strips 297 or the like against which the wheels 293 bearwhen applying stripes of heated wax to opposite sides of the liner.These strips 297 are secured in any suitable manner in grooves formed inopposite sides of the forms 40, respectively.

The wax in the receptacles 295 is, in accordance with the presentinvention, heated to maintain the same in a melted condition forapplication by the wheels 293 to the liners or containers, and said waxis preferably heated electrically in the following manner. The contact255 on the switch panel 173 has connected therewith a bus bar 298 whichis also connected with a contact 299 on said panel (Fig. 15). The panel173 has mounted thereon a switch 300 movable into engagement with the,contact 299 and connected with'one end of a lead wire 391. The lead wire301 has branches 302 connected with corresponding ends of resistanceelements 303 forming parts of heaters 304 secured in any suitable manneron the bottoms of the wax receptacles 295 and serving to heat the waxtherein. The resistance elements 303 are insulated in any suitablemanner from the heaters 30% and the re= ceptacles 295. The opposite endsof the re= sistance elements 303 are grounded in any suit able manner onthe receptacles 295, and when the switch 300 is closed, current will besupplied to the resistance elements 303 by the describedmeans for thispurpose, and the heaters 304 will heat'the receptacles 295 and the waxtherein.

Additional heaters are preferably employed on the sides cfthe waxreceptacles 295, these additional heaters preferably being of the sametype as the heaters 304 and supplied with electrical current as follows;The contact 299 on the switch panel 173 has connected therewith a busbar 306 which is also connected with a con tact 307011 said switchpanel. The switch panel 173 has mounted thereon a switch 303 movableinto engagement with the contact 307 and con nected with one end of alead wire 309. This lead wire 309 has branches 399' connected withcorresponding ends of resistance elements 312 forming parts of heaters311 secured in any suitable manner on opposite sides of the receptacles295. The resistance elements 310 are insulated in any suitable mannerfrom the heaters 311. and the receptacles 295, and the opposite ends orsaid v through the described means for this purpose.

The heaters 311 will thus heat the receptacles 295 and melt the waxtherein, the provision of heaters on the sides, as well as the bottomsof the receptacles 295 enabling the wax to be melted quickly when themachine is started. After the wax in the receptacles has been melted,the bottom heaters 304 or the side heaters 311 may be thrown out ofoperation, so that one or the other serves to keep the wax in thereceptacles 295 in melted condition. All of the heaters may, however, beemployed, if desired, in accordance with the particular conditions ofoperation of the machine and the particular nature of the wax employed.

After the closed ends of the liners or containers are heat sealed, theforms and the liners or containers thereon pass one after another undera cooling plate 312 (Figs. 2, 4 and 6) which cools the sealed ends ofsaid liners or containers. This plate 312 is provided therein with airvents or openings 312 and isyieldably supported, as by a bolt 311.2 anda spring 312, on an extension 312 of one of the cross members 217. Thebolt 312 is threaded in a suitable opening in the plate 312 and extendsupwardly through a suitable opening in the extension 312 The spring 312is mounted on the bolt between the extension 312 and a collar 312 onsaid bolt. The bolt is provided above the extension 312 with a nut 312and the plate 312 has secured to, or formed integrally'therewith, acurved end 3i2 under which the forms 40 and the liners thereon pass inengagement with said plate. The forms 90 and the liners thereon pass oneafter another to mechanism for forming cartons thereon as follows.

The cartons B (Fig. 10) are made from blanks 313 which are fed into thepath of travel oi the forms 30 one after another and formed intocontainers thereon by mechanism which is preferably operated, mounted,and constructed as disclosed in Patent No. 1,674,921 granted June 26,1923, to G. A. Robinson, and in my co-pending application Serial No.413,349, filed January 3, 1930. Accordingly, the shaft 30 has fixedthereon a sprocket 314 around which passes a chain 33.5 which alsopasses around a sprocket 313 which is fixed. on a shaft 317 extendingtransversely of, and journalled in suitable hearings on spaced frames313 and 319 (Figs. 3 and 5). The frames 313 and 319 are bolted orotherwise suitably secured on frame members 320 and 321 supported attheir ends by standards 322 which, in turn, are bolted or otherwisesuitably secured to the machine foundation 9.

The frame members 320, 321 extend forwardly over the liner and cartonmaking machine and are supported thereon by cross members 323 extendingtransversely of said frame members and bolted or otherwise suitablysecured thereto (Figs. 2 and 3). The cross members 323, in turn, extendtransversely of, and are bolted or otherwise suitably secured to, frames32% and 325 mounted on the side frame members 5 and 3 and bolted orotherwise suitably secured thereto in any suitable manner. Mounted onthe frames 313 and 319, the standards 322, and base plates 326 for thelatter, is an elevator including endless driven chains 327 operated fromthe shaft 317, as disclosed in application Serial No. 418,349 abovereferred to, and supporting a stack 328 of carton blanks 31.3 which areseparated one after another from the top of the stack and fed forwardlyin like-manner by a separator roller 329. This roller 329 is supportedin engagement -with the .top of-the stack by a weighted yoke joumalledon theshait an, and said roller is driven from said shaft by'suitablegearing for.

l the glue wheel shaft 346 and mounted in any this purpose. Journalledon the frame319, is a short vertical shaft 330 which is driven in anysuitable manner from the shaft 317 and carries a bevel gear 331 whichmeshes with a similar gear 332. The gear 332 is fixed on a horizontallyarranged cam shaft 333 extending longitudinally of'the-frame member 21and journalled in suitable bearings thereon. The elevator 327, theseparator roller 329, and the cam shaft 333 are thus operated by theconnections therefor with the shaft 30.

The blanks 313, separated andforwarded successively from the top of thestack by the roller. 329, are delivered thereby one after another be-.

tween upper and lower feed tapes 334 and 335 respectively that passaround suitable rollers which are arranged at opposite ends of saidtapes and journalled in suitable hearings on brackets bolted orotherwise suitably secured to the frame bender 337 and a sideregistering device 338 for registering the blanks therewith. This fiapbender 337 and the side registering device 338 335to the grippers 340 ofa turning roll 341 comprised by wheels on disks fixed on a shaft 342extending transversely of the frame members 320, 321 and journalled insuitable bearings thereon (Figs. 2 and 5). The turning roll 341 and thegrippers 340 thereon, are operated by the mechanism for this purposedisclosed in Patent No. 1,674,921 and including a bevel gear 343 fixedon the shaft 342 at one end thereof and mesh ing with a'similar gear 344fixed on the driven cam shaft 333. Each blank 313 seized by the grippers340 of turning roll 341 is turned thereby from a substantiallyhorizontal position to a substantially vertical position and feddownwardly into the path of travel of one of the forms 40. Duringdownward travel of the blanks, the flap 339 of each blank has appliedthereto adhesive, through the medium of glue mechanism which is mounted,constructed, and operated as disclosed in Patent No. 1,674,921. Thisglue mechanism includes a glue wheel 345 fixed on a shaft 346 and tumingin glue contained in a box 347 supported by a bracket 347' on the frame6 of the machine (Figs. 2 and 4). The shaft. 346 is journalled insuitable hearings on the glue box bracket 347, and said shaft has fixedthereon a sprocket 3413 around which passes a chain 349. The chain 349also passes around a sprocket 350 fixed on the continuously rotating camshaft 333, and it will thus appear that the glue wheel 345 is driven bythedescribed driving connections therefor with said cam shaft. The gluewheel 345 applies glue to theperiphery of" a roller 351 driven bysuitable gearing from suitable manner on the glue box bracket 34?. Asecond roller 352 mounted in any suitable man- -the blank is foldedaround the front and opponer on the glue box bracket 347', is movedtowardand away from the roller 351 by suitable mechanism for thispurpose operated from the cam shaft 333, as disclosed in Patent No.1,674,921. As the blanks 313 are fed downwardly from the turning roll341, they pass between a guide plate 353 and guide bars 353' disposedvertically in spaced relation and supported in any suitable manner onthe side frames 5 and 6 of the machine. As each blank 313 passes throughthe guides 353, 353', the bent flap 339 passes between the rollers 351and 352, and adhesive is applied to said flap.

- The blanks 313 are fed downwardly between the guide plate 353 and theguide bars 353', by g rollers 354 and 355 extending therein. The rollers354 are fixed on a shaft 354 journalled in suitable bearings on theguide plate 353 and extending transversely thereof. The shaft 354' andthe rollers 354 thereon are driven from the shaft 342 by means of asprocket 356 fixed on the shaft 354', a chain 35'? passing around saidsprocket, and a sprocket 358 fixed on the shaft 342 and around which thechain 357 also passes. The rollers 355 are fixed on a shaft 359 jour-.nalled in arms 360 pivoted on the guide plate 353 and said shaft andsaid rollers are driven through suitable gearing from the shaft 354'. v

The plate 353 is provided in the bottom portion thereof with an opening362 through which the forms '40 and the liners or containersthereontravel one after another. As the blanks 313 are fed by the rollers 354,355 one after another between the guide bars 353' and the plate 353,

they are seized by feed rollers 363 and 364 which 116 feed each blankdownwardly onto stops 365 mounted in any suitable manner on the plates361 at opposite sides of the openers 362 therebetween. The feed rollers363 extend through suitable openings in the plate 353 and are drivenfrom the shaft 354' which, for this purpose, has fixed thereon asprocket 366. Passing around the sprocket 366 is a chain 367 which alsopasses around a sprocket 368 that is fixed on a shaft 369. The rollers363 are also fixed on the shaft 120 369, and said shaft extendstransversely of the machine and is journalled in suitable hearings onthe side frames'5 and 6 thereof. The rollers 364 are driven from theshaft 369 by suitable gearing for this purpose, and said rollers arefixed on a shaft 370 extending transversely of the machine andjo'urnalled in suitable bearings on arms 361 mounted in any suitablemanner on the plate 353. v s

As each carton blank 313 with the side flaps engages the same and forcesthe blank between rollers 371 between which the forms 40 travel.

These rollers 3'71 are journalled in any suitable manner on the plates353, and as a form with a liner or container thereon in a carton blankin front of the same passes through said rollers,

The folder 373 is operated, mounted, and constructed in substantiallythe same manner as the rear panel folder disclosed in Patent No.

1,674,921. Accordingly, the shaft 34 has fixed thereon a sprocket 374around which passes a chain 375 that also passes around a sprocket 376fixed on a shaft 377 extending transversely of the machine andjournalled in suitable hearings on the side frames. 5 and 6 thereof(Figs. 2 and 3). Fixed on the shaft 377 is a sprocket 378 around whichpasses a chain 379 that also passes around a sprocket 380 fixed on ashaft 381 extending transversely of the machine and journalled insuitable bearings on the side frames 5 and 6 thereof. The shaft 381 isthus driven continuously through the described driving connectionstherefor with the shaft 34, and said shaft 381 constitutes the maindriving shaft for devices that impart the described travelling andfolding motions to the folder 373.

The forward and rearward movement of the folder 373 is derived from theshaft 381 through a bevel gear 382 which is fixed on said shaft andmeshes with a similar gear 383. The bevel gear 383, in turn, is fixed ona shaft 384 at the lower end thereof, said shaft being journalled insuitable bearings on the side frame 5 of the machine. Fixed on the upperend of the shaft 384 is. a sprocket 385 around which passes a chain 386that also passes around a sprocket 387 fixed'on a, short vertical shaft388 at the lower end thereof. This shaft 388 is journalled in a suitablehearing on a box-shaped bracket 389 which is bolted or otherwisesuitably secured to the side frame (Figs. 2 and 5). Fixed on the upperend of the shaft 388 is a sprocket 390 around which passes a chain391that also passes around a sprocket 392 fixed on the upper end 'of ashort verticalshaft 393.

The free end of thearm 402 has connected therewith, as by a universal connection, one endof a link 404 the opposite end of which is likewiseconnected with onearm 405 of a bell crank 406. This bell crank 406 is flxedon a rockshaft407' extending in parallel relation with the guide rod 398 and'joumalled in suitable bearings onthe bracket 389. One end of therockshaft 407 has fixed thereon an arm 408 with which is connectedoneend of a rod 409 the opposite end ofv which is connected with theother arm 410 of the bell crank 406. The rod 409 extends between rollers411 journalled in spaced relation on a slide 412 extending diagonallyacross the carriage 397 and guided thereon in any suitable manner. Thefolder 373 is pivotally mounted at 413 on one end of the slide 412, andsaid folder receives its inward and outward movement as said slide isreciprocated through the described connections therefor with the shaft381.

The folder 373 is also swung, at proper intervals, to swing in and sealthe panel 372 of the carton, and for this purpose, the folder hasconnected therewith one end of an arm 414 the opposite end of which ispivotally connected with one end of a link 415. The opposite end of thelink 415 is pivotally connected with the guide for the slide 412. Theforms 40 and the folder373 are operated in such timed relation, that aseach form approaches the folder, the latter moves inwardly on the backof the form to engage the panel 372 of the carton on the outer rearcorner of the form and thus crease the corresponding corner of thecarton thereon. The folder is then swung, by the arm 414 and the link415, moving the panel 372 onto the form over the glued'sealing flap 339of the carton and sealing said panel thereon. The folder then travelsforwardly with the form pressing the overlapping panel and flap tosecure them together, whereupon the folder is swung away from the formand then moved outwardly and rearwardly for subsequent movement to foldin the rear panel of the carton'on the next form 40, in the same manner.'It will thus appear, that the folder 373 acts to side-seal This cam 399has engaged in the cam I the cartons on the form successively as thelatter travel in like manner past said folder.

After each carton is side-sealed on the form and secured to the liner,as previously described, one end of the carton is closed and sealed overthe closed and sealed end of. the liner or container. Accordingly, theend flap 416 of the car ton is folded down on top of the liner and formby a stationary folder 417 (Fig. 2) under which the forms travel oneafter another. This folder 417 is supported in any suitable-manner, asby a cross member extending transversely of the machine and secured tothe side frames 5 and 6 at the tops thereof. The opposite end flaps 418of the carton is folded down on top of the form and the liner orcontainer by a'movable folder 419 carried by an arm 419' fixed on arockshaft 420 extending transversely of the machine and journalled insuitable hearings on the side frames 5 and 6 of the machine. fixedthereon an arm 421 with which is pivotally connected one end of a link422. The opposite end of the link 422 is pivotally connected with an arm423. This arm 423 is pivotally mounted at 424 on the side frame 6 of themachine and This rockshaft 420 has carries a roller 425 which is engagedin the groove of a closed cam 426. The cam 426 is fixed on the shaft 34at the end, thereof opposite that carrying the sprocket 33, and said camis so shaped that as. each carton passes under the folder 419,

the same is moved to fold down the flap 418,

through the described connection for said folder with the cam 426.

As the carton flaps 416 and 418 are folded by the described means forthis purpose, and the form with the carton thereon moves forwardly, saidflaps are held down by a suitable guide rail for thispurpose and theside flaps 427 and-428 of the cartonare bent outwardly by the folder 417and engaged under guide rails 417 supported on the machine frame work inany suitable manner. The flaps 427, 428 are thereafter engaged by gluewheels 429 which apply glue to said flaps. and said glue wheels arefixed on a shaft 430 and extend within boxes 431 containing glue orother adhesive. The glue boxes 431 are mountand 6 of the machine,-andthe'shaft 430 extends transversely: of, and is journalled in suitablebearings, on said glue boxes. The shaft 430 and i the glue wheels 429thereon are preferably driven from the shaft 20 which, for this purpose,has fixed thereon .a pinion 432 which meshes with a gear 433 that isfixed on the shaft 430.

It will appear, from the foregoing, that glue is applied to the flaps427, 428 of the cartons as the forms and cartons thereon travel oneafter another past the described means for this purpose. The forms andcartons, after passing the glue wheels 429, turn downwardly and travelin the opposite direction past stationary folders 434 and 435, thefolder 434 serving to fold in and seal the flap 427 on the flaps 416 and418, and the folder 435 serving to fold in and seal the flap 428 on theflap 427 (Fig. 3). Thereafter, the

forms and the cartons thereon travel over a press.

mechanism indicated broadly at 436 (Figs. 2 and 3) which acts to pressthe sealed ends of the cartons prior to delivery of the same-from the 45forms'in a manner to-be presently described. This press mechanism 436may be of any suitable or well known construction, and is supported inany suitable manner on the side frames 5 and 6 of the machine betweenthe same, and at the bottoms thereof. The movable parts of the pressmechanism are driven by a belt 436' from the shaft 377.

It will appear, from the foregoing, that as the forms andcartons'thereon travel one after another past the folders 434, 435 andover the press mechanism 436, the flaps 427 and 428 of successivecartons 'will, be closed and sealed, as described, whereupon the cartonsmaybe moved one after another from the successive forms 40. Removal ofthe lined cartons from the forms may be accomplished byblasts of airdelivered thereto, or by mechanical means,.as desired. In the embodimentof the invention herein shown, the lined cartons are removed from theforms 40 by inclined guide rails 437 (Figs. 1 and 2) extending from oneend .of the press mech- Y anism 436 to one end of the machine proper andarranged to engage the open ends of the lined cartons successively tostrip them one after anotherfrom the successive forms 40. The 'in-' 440finally strip the cartons from the forms 40 for delivery onto a cartontransporting means 441 or to any other suitable point of delivery. Thecarton transporting means 441 is driven by a chain 442 from the shaft98. and the guides 439 and 440. are secured in any suitable manner onthe ways 39 and the brackets 37, respectively.

The operation of the entire 'machine will be readily understood from theforegoing, and may be briefly summarized as follows. A waxed liner 42cut from the web and delivered onto the stops 86 by the described meansfor this purpose, is engaged by one of the forms 40 which travelsthrough the rollers 87 and folds the liner around the form. Incontinued, travel of the form, one

of the folders 91 and one of the folders 93 fold in the rear panels orportions 90 and 92 of the'liner and heat seal the overlapping parts ofsaid panels orportions. As the form 40 with the side-sealed linerthereon passes the folders 219 and 221 the latter fold in the front andrear end portions 218 and 220 of the liner, whereupon the form and theliner pass the devices 207, 237, 208 which fold in the side portions 235and 236 of the liner.

In the continued movement of the form 40 and the side-sealed liner orcontainer thereon, the same pass the wax applying wheels 293 which applystripes of hot wax to opposite sides of said container or liner,respectively. In the meantime, the form 40 with the side-sealed andendclosed liner or blank thereon passes under the rollers 251 and 263which heat seal the closed end of the liner or container, wherepon theform with liner and secured thereto by the stripes of wax applied on thelatter. Thereafter, the form with V the liner and carton thereon passesthe folder 373 which folds in and seals the panel 372 of the carton onthe flap 339 thereof. The form 40 with the side-sealed and lined cartonthereon then passes the several devices for'end closing and sealing thecarton, whereupon the form and the carton, pass over the press mechanism436 and the carton is thereafter stripped from the form by the'describedmeans for this purpose. The forms 40 travel continuously one afteranother past the various liner and cartonforming devices and havelinedcartons formed thereon one after another in the manner abovepointed out. 1
